LUBBOCK, Texas -- With a school-record crowd of 19,500 in attendance, Texas Tech finished its spring schedule with a two-hour spring game at Jones AT&T Stadium. Here’s what we learned from the game:

Best offensive performance: A bulked-up Davis Webb put on a show, completing 25 of 37 passes for 354 yards and four touchdowns. Most of his reps came in the first half, and he showed off some impressive touch on his TD throws -- his 23-yard score to Bradley Marquez under pressure was a gem. The sophomore QB even added a long touchdown run that was called back. And for what it’s worth, Webb was even better in Tech’s previous open scrimmages this spring. He’s just no fun to defend, and his coaches will vouch for that. “He’s driving me to drink Pepto-Bismol,” defensive coordinator Matt Wallerstedt joked after the game.

Best defensive performance: Got to give credit to Josh Keys for being opportunistic. The junior college transfer safety scooped up a fumble that rolled right to him at the end of the first quarter and scored from 22 yards out. That takeaway, a strip after a screen pass, had to be encouraging for a defense that ranked third-worst in FBS with a turnover margin of minus-14 last season. Redshirt freshman linebacker Collin Bowen also snagged an interception.

Best debut: This wasn’t a true debut, since he did play some special teams last season, but receiver Brent Mitcham made a nice impression. The senior spent three years on the scout team and had a minimal role in 2013 but stepped up on Saturday with a game-high six receptions for 80 yards. The best of the bunch was a catch over the middle that Mitcham turned and took down the sideline for a 41-yard gain.

Notable play: On a play-action pass in the first quarter, Webb rolled right, planted and fired a pass toward the opposite hash to a wide-open Jakeem Grant. The speedster made a defender miss along the sideline and cut across the field for a 75-yard touchdown. Grant finished with 105 yards on five receptions.

Developing storyline: Help is still on the way for this Texas Tech defense. Much will be expected of ESPN 300 cornerback signee Nigel Bethel II and junior college transfers Rika Levi, Brandon Thorpe and Marcus Smith when they arrive this summer. You should see a few more freshmen (maybe safety Payton Hendrix and linebacker Dakota Allen) fight their way into the two-deep. “As all of our guys get here in June and we have a monster summer, this thing will look a little different than even what it looked like today,” Wallerstedt said.

Biggest question answered: Can Texas Tech’s receivers make up for the loss of Eric Ward and Jace Amaro? From a statistical standpoint, they will go down as two of the all-time greats among Red Raider pass-catchers, but Webb is confident this group can be even better. In addition to Grant and Marquez, he singled out Reginald Davis, D.J. Polite-Bray, Devin Lauderdale and Derreck Edwards as playmakers he’s excited to utilize this fall. “This is the fastest receiving group I’ve known since I’ve ever watched Texas Tech football,” Webb said.

Quotable: "We have a lot more confidence than last year. Last year, we just tried to install and the guys are trying to figure us out and figure out our expectations. They know what they can be after that bowl game and carry that confidence over to being a top-15 team. They know what they can be if they put it all together, so that's exciting." -- Texas Tech coach Kliff Kingsbury
